In this article I'll describe the installation of Oracle Database 11g Release 2 (11.2.0.2) on Solaris 10 (x86-64).
The article is based on a default server installation as shown here. Alternative installations may require a different setup procedure.

If you've performed a default installation, it is likely that the only kernel parameter you need to alter is "max-shm-memory" to meet the minimum installation requirements. To check the current value issue the following command.

Add the "SUNWi1cs" and "SUNWi15cs" packages using the "pkgadd" command.

# pkgadd -d /cdrom/sol_10_910_x86/Solaris_10/Product SUNWi1cs SUNWi15cs
